Ruby
1

Hi all
Hi guys i am new to ruby,i am searching for a ruby method which
gives the same output as given by Integer.toHexstring(int),but unable
to find any methods.

Is there is a ruby method or can i call this java method from a ruby
file and passing the parameter and get the output from this java
method.

Any help is greatly appreciated.

Thanks

if you don’t like the ruby way , you could call that method directly
from jruby :slight_smile:

irb(main):001:0> 123.to_s 16
=> “7b”
irb(main):003:0> “%x” % 123
=> “7b”
irb(main):004:0> sprintf “%x”, 123
=> “7b”
irb(main):005:0> printf “%x\n”, 123
7b
=> nil
